Yes and no. Morgoth weakened overtime. Sauron poured his power into the ring, but Morgoth poured his power into the earth itself (and his “creations” like orcs and werewolves) corrupting it. Of course, once he did this he was no longer able to access his power and so, at the time of his defeat, he was greatly weakened. Tolkien himself has said Sauron at his most powerful was perhaps greater than Morgoth at his weakest. Of course, when Morgoth was at full power, he was way beyond Sauron ever was or could be. At that time he was titanic being, a literal dark god, capable of shaping the world and matching the Valar (the gods) on his own.
